计数型数据性能曲线介绍内容提要：
什么是“a”值？
The “a” value is the number times a part is accepted.
“a”值是一个零件被接受的次数。
The smallest (largest) part must have an “a” value = 0.
This means that the part was never accepted by the gage.
最小（最大）零件的“a”值必须是0。
这意味着该零件永远不会被量具接受。
The parts from the center of the distribution should have an
“a” value = 20. This means that this part was always
accepted by the gage.
位于分布中心的零件的“a”值应该等于20。这意味着该零件
一直会被量具接受。
